Correct answer: A
In sparse population, services may need different delivery methods. Exam tip: write low-density service strategies.

Population Density
जनसंख्या घनत्व
In this Class 9 Geography topic from the chapter Population, students learn how population density measures the number of people living in a unit area, usually per square kilometre. They explore the population-density formula, interpret maps and data, and compare densely and sparsely populated regions. The topic also explains how relief, climate, soil, water availability, transport, industries and employment influence settlement patterns and the distribution of population in India and around the world.

If an area has high density and high air pollution, which analysis is correct?
Correct answer: A
Density can link with urban activities and transport pressure. Exam tip: check combined urban factors.
View question detailsIf Region A's population remains same and its area becomes one-fourth, how can density change?
Correct answer: A
With same population and reduced area, density increases inversely. Exam tip: remember inverse relation.
View question detailsIf population doubles and area becomes four times, what will happen to density?
Correct answer: A
Area has increased in a larger proportion than population, so density will decrease. Exam tip: compare ratios.
View question detailsIf density is rising in a city but people are settling in cheaper outer areas, what pattern can form?
Correct answer: A
Housing cost and transport can change a city's density structure. Exam tip: remember the urban fringe concept.
View question detailsIf density temporarily rises greatly during tourist season, what difference from permanent population density should be understood?
Correct answer: A
Tourist crowd can pressure services but differs from permanent population. Exam tip: write temporary pressure separately.
View question detailsIf an area has high density and poor drainage, which urban risk can increase?
Correct answer: A
Poor drainage in dense areas increases waterlogging and disease risk. Exam tip: connect sanitation and drainage with density planning.
View question detailsIf an area has low density but very fertile cultivable land and irrigation is increasing, what future change is possible?
Correct answer: A
Farming opportunities and water facilities can attract settlement. Exam tip: check future density potential.
View question detailsIf an area has population of thirty two lakh and area of six thousand four hundred square kilometres, what will be its density?
Correct answer: B
Dividing thirty two lakh by six thousand four hundred gives five hundred. Exam tip: convert complex numbers into simple ratios.
View question detailsIf an area has high density but high per capita income too, what conclusion is more balanced?
Correct answer: A
The balanced conclusion is that high population density should not automatically be treated as a sign of poverty or poor living conditions. A densely populated area may still provide a good standard of living when per capita income is high and services such as health care, education, housing, and transport are adequate. Option B is incorrect because density alone does not prove poverty. Exam tip: when evaluating population density, connect it with income, resources, and public services.
View question detailsIf an area has low density but people are not scattered and are settled in a few small centres, which statement is correct?
Correct answer: A
Small centres can be dense within low average density. Exam tip: study settlement pattern and density together.
View question detailsIf an area has very high population density and land value is rising rapidly, what relation is possible?
Correct answer: A
High density can affect demand and value of limited land. Exam tip: also check economic effects.
View question detailsIf an area has low density but relief delivery is difficult during disasters, which density-related planning challenge appears?
Correct answer: A
In remote low-density areas, distance and time for relief can be challenging. Exam tip: connect low density with disaster planning.
View question detailsIf an area has high density but population growth rate is declining, which indicators should be read separately?
Correct answer: A
Density shows present condition while growth rate shows future pace. Exam tip: keep both indicators separate.
View question detailsIf density around an area rises after a commercial centre develops, which factor is working?
Correct answer: A
Trade and services can attract people to settle around the centre. Exam tip: write economic pull factor.
View question detailsIf an area has low density but all people are settled along an industrial corridor, what does it indicate?
Correct answer: A
An industrial corridor can create local concentration even in low average density areas. Exam tip: identify corridor-based patterns.
View question detailsIf an area has population of forty eight lakh and area of eight thousand square kilometres, what will be the density?
Correct answer: B
Dividing forty eight lakh by eight thousand gives six hundred. Exam tip: write the correct unit with calculation.
View question detailsAt expert level, what is the correct order for analysing population density?
Correct answer: A
Expert analysis includes meaning and use along with calculation. Exam tip: write both formula and interpretation.
View question detailsIf population remains the same in an area but safe habitable area decreases due to floods, what will happen to real density pressure?
Correct answer: A
When safe habitable area decreases, the same population concentrates in a smaller area. Exam tip: understand the difference between total area and safe habitable area.
View question detailsWhy do regions with extremely cold climates generally have low population densities?
Correct answer: C
Extremely cold regions may have very low temperatures, frozen ground, heavy snow, and a short growing season. These conditions make farming difficult because crops have less time to mature. Construction and transport may cost more, and everyday activities require additional heating, equipment, and protection. As a result, fewer kinds of work are possible and living expenses may be high, so people are usually spread thinly.
Option C is correct because harsh temperature limits both settlement comfort and economic opportunity. The other choices describe conditions that do not generally explain low density: cold regions do not always have fertile soil, transport is not always easy, and water availability alone does not guarantee settlement. Some cold areas can be populated, but the question asks about the general pattern.
